Stewart went 3-for-6 with one RBI and two runs scored in Saturday's 11-5 win over the Diamondbacks.
The Reds' first four hitters in the lineup all had multi-hit efforts, going a combined 13-for-22 with eight RBI. Stewart was the only one of the quartet who didn't have an extra-base hit in this contest, but it was still a strong game. He's batting .293 (24-for-82) in August and is up to a .262 average, .809 OPS, 27 home runs, 97 RBI, 72 runs scored, 24 doubles and 12 stolen bases over 130 games this season.
